Nemesia plant named ‘Dannemes4’

ABSTRACT

A new and distinct  Nemesia  cultivar named ‘Dannemes4’ is disclosed, characterized by having clear white flowers flowers, upright plant habit, early flowering, and a high temperature tolerance. The new variety is a  Nemesia,  normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Nemesia fruticans.

Variety denomination: ‘Dannemes4’.

BACKGROUND OF THE INVENTION

The new Nemesia cultivar is a product of a planned breeding programconducted by the inventor, Gabriel Danziger, in Moshav Mishmar Hashiva,Israel. The objective of the breeding program was to produce newvarieties of Nemesia for commercial introduction. The seed parent is theunpatented, proprietary seedling variety referred to as Nemesiafruticans ‘NE-Z-21.’ The pollen parent is unknown as the new variety isthe result of an open pollination in which the male parent cannot beidentified. The new variety was discovered in April 2006 by the inventorin a group of seedlings resulting from that crossing, in a commercialgreenhouse in Moshav Mishmar Hashiva, Israel. Asexual reproduction ofthe new cultivar ‘Dannemes4’ by vegetative cuttings was first performedat a commercial greenhouse in Moshav Mishmar Hashiva, Israel inSeptember 2006. Subsequent propagation has shown that the uniquefeatures of this cultivar are stable and reproduced true to type onsuccessive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Dannemes4’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Dannemes4’ These characteristics incombination distinguish ‘Dannemes4’ as a new and distinct Nemesiacultivar:

-   -   1. Vigor.    -   2. Pure white flower color.    -   3. Early flowering.    -   4. High temperature tolerance.

Plants of the new cultivar ‘Dannemes4’ are similar to plants of theparent, Nemesia fruticans ‘NE-Z-21’ in most horticulturalcharacteristics, however, plants of the new cultivar ‘Dannemes4’ have adifferent color flower.

Commercial Comparison

Plants of the new cultivar ‘Dannemes4’ are best compared to thecommercial variety ‘Balarwite,’ U.S. Plant Pat. No. 17,592. Plants of‘Dannemes4’ are similar to plants of ‘Balarwite’ in most horticulturalcharacteristics, however, plants of the new variety are taller andflower earlier than plants of ‘Balarwite.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘Dannemes4’ grown in a greenhouse, in a 16 cm pot. Ageof the plant photographed is approximately 5 weeks from a rootedcutting, with 2 rooted cuttings planted in the pot shown.

FIG. 2 illustrates in full color a close up of a typical bloom of‘Dannemes4.’

The photographs were taken using conventional techniques and althoughcolors may appear different from actual colors due to light reflectanceit is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart (2001 edition) and The RoyalHorticultural Society Mini-Colour Chart (2005 edition) except wheregeneral terms of ordinary dictionary significance are used. Thefollowing observations and measurements describe ‘Dannemes4’ plantsgrown in a greenhouse in Moshav Mishmar Hashiva, Israel. The growingtemperature ranged from 20° C. to 28° C. The greenhouse is un-shaded,giving bright, normal sunlight conditions. Measurements and numericalvalues represent averages of typical plant types.
